The Kremlin said on Monday that Russia was still ready to honour agreements with Ukraine on a new prisoner of war exchange and on the repatriation of dead soldiers despite what it said was Kyiv's failure to so far honour its side of the bargain.

Russia said Sunday that trains carrying more bodies of Ukrainian soldiers were due to depart towards the Ukrainian border, escalating a spat with Kyiv over a prisoner of war swap.

MOSCOW/KYIV — A large-scale prisoner exchange between Russia and Ukraine — the only concrete outcome of peace talks — was thrown into doubt on Saturday after Moscow and Kyiv accused each other of delaying and thwarting the swap.
